Physicists detect 'charge instability' across all flavors of copper-based superconductors

Physicists have detected 'charge ordering' in electron-doped cuprate superconductors for the first time. Charge ordering is a ripple-like instability at the electron level that competes with superconductivity and likely suppresses the temperature at which materials demonstrate superconducting properties. Until now, researchers had only observed the phenomenon in other forms of cuprate materials.
